I have a 91 Acccord EX 2dr that won't start when it is over 65 degrees
outside. The car only does this when it is hot outside. The car will sit
all night and when i go to start it to commute to work it won't start.
This problem has been on and off for the last three years. When i try to
start it all it will do is act like it isn't getting gas (but it is) and if
I take off the distributer cap the 4 prongs will look like the are fouled
out (oxidized). If I scrape the oxidation off ot the prongs and wait
twenty minutes it starts with no problem, smokes a tiny bit, then takes me
the 140 miles to and from work. I have tried new: wires, plugs, cap, rotor
and it still happens from time to time and every time I take it to the
dealer for diagnostics they say nothing is wrong. Something has to be
wrong if it doesn't start. right??

Resolder the main relay. Very common.

I have a buddy at work who had the exact same issue with his early 90s
Accord a couple years back and had a $100 part replaced that fixed the
problem. Likely what Steve posted here. I'll check with him tomorrow and
post back.

Main relay? enables the fuel pump to keep enough pressure to run the fuel
injection. Has problems with cold solder joints,causes intermittent
operation,heat-related.

________________________

If you need to use the car tomorrow, before fixing the relay, you can
smack the dash with the switch in position II, and you'll hear the fuel
pump run for four or five seconds . . The car will now start. When the
car is warm, it's the vibration that keeps it going once the engine starts.

After you got all the good replies, here's something that made me wonder...

Where in the world do you live that 65 degrees (assuming Fahrenheit) is
considered *hot outside*?

Yep, I asked my buddy today and the main relay issue mentioned by several
people here is exactly what he had fixed a couple years back.

Thank you for the info on my problem. I spoke to a Honda tech and he told
me basically the same thing. Oh yeah, in upstate New York 65 is a
beautiful day.
